IMPROVEMENT I'PULLING-MILLS,

l tlge .Stimme mach tu la ythat dans what ma mating. glitt mi tintura To ALL WHOM IT MAY CONGERN:

Be it known that I,.ERNsT Gassner-R, `ot' Aue, in theKingdom of Saxony, have inventeda new and improved Fulling-Machine; and I do hereby declare the following to be a full, clear, and exact description thereof, enabling those skilled in the art' to make and use the samc,reference being had to the, accompanying drawing, forming partof thisspecificatiomin which drawing v v Figure lvreprcscnts an end view of this invention. t

Figure 2 is a plan or top View of the same, l

Figure 3 is a transverse vertical section of the same.

Similar letters indicate corresponding parts.

. This vinvention consists, first, in 'the arrangement of an adjustable fulling-stock or tub, in` combination-with one o r more oscillating or reciprocating beaters, in such a manner that 4said tubcan be moved closer to or further from the beater or beaters, according to the quantity of goods to be fulled;` second, in the arrangement of a spring or Weight, acting on the fulling-stock or tub, and forcing the same up against theb-eater or beaters with a yielding pressure, in such a manner that said tub iscapable of adjusting itself tothe larger or smaller quantity of goods to be lacted upon by the beaters; third, in the arrangement of two lor more beaters in pa.irs,each pair being connected together by springs, and acted on by a common eccentric, in such a mannerthat said beaters are alternatolyforced intoone tub and then into the other, and a,double-acting-fullinglmachiue is obtained, which occupies 'comparatively little room,l and produces adarge' amount of work. Y

A represents the fulling-stock or tub, whih-is suspended by means of arms, A', from a shaft, x, so that it is free -to oscilla-te on said shaft. Onv the samclyshaft oscillate the'be'aters B, and' under the. tub entends a shaft, d, on which are mounted two gear-\vheels, whichmesh into toothed segments c secured to the tub A, so that, by turning 'the shaft al, the tub A is, moved uniformly towards or from the beaters, and thus adjusted in the desired position'.

Instead of the gear-wheels and toothed segments,'howevemsmple drums or pulleys could be used, which would connect with the tub by cords or bolts. if 'desired,'any other suitable mechanism might be substituted for the purpose of adjusting the tub.`

On the shaft d issecuredfa ratchet-wheebf, anda movable lever, g, which is connectedto c. spring, z', and which carries a click, that gears intov ratchetwheel f, whereby the power o f the spring z' is transmitted to the shaft d, and through it to the tub. I v i By |these means the tub'is rendered yielding, so that it can adjustitself according to the quantity ofgoods to be acted lon by the beaters.

' The mechanism employed for-making the .tub yielding or self-adjusting may also be arranged as follows: Between the frame, whichformsthe bearings for-the aiile x ofthe tub, is situateda shaft, g, on which is 'mounteda wormlwheel, r, which gears into the worms s1 On said shaft are also secured two gear-Wheels, Z, which mesh into toothed segments ja, which turn loosely on the shaft x', and connect with the tub A by means ofthe springs U.

By turning the worm s the tub A ismovcd towards or from the beater or beaters, 'and by the action of the springs 'u said tub is rendered yielding. d

i For the springsz' crv, weights might be substituted', which, when properly arranged,would produce the same effect as said springs.' Y Y i l V- The tub A is provided with ailid, P, which ishinged, and so arranged that it pressesdown upon the goods to be fulled by its inherent gravity, and that it closes the tub-'during the operation of fulli'ng, while it yields to the action of the beaters, andallowsof being thrown open, Awhile said beaters are in. motion, for the purposecf' introducing or removingthe goods. i A

In the drawing, the lid is shown as being made in two parts, but it might be made in oneormore parts.

Said lid may be provided with a suitableiaperture or vapertures,'for the introduction of soap' and Water during L the operationoffullng.. A i

The length of the tub Ais equal-to the width of`thefc1oth or other fabric to be foiled, so that, during the operation of falling, all folds inalongitudinal direction can be,a.voided. The number of beaters is'incresed to four or more in each tub, and the motion of the beatersis alternating, so that-the operation'of the falling-machine is rendered steady, and that thc'driving-power is applied in the most economical manner.

The beaters B `are arranged in pairs, each pair bei'n'g' connected by apeculiar spring, K. This spring consists of two parts, which are' connected together by'a. screwpK., and `which-are hinged lto thebeaters, in such-a.

,maynner that they keep the-backs of said bentersin contct with an'eccentric-disk, L, whiclr'ismounted on the driving-shaft M, and vthatfeach pair of bceters is operated by one eccentric.

By means of the screw K the beaters 'can be kept-in close contact with their eccentric; .On the driving shaft M is also mounted the iiy-wheel N, and the festland loosepulleys O, by-whichsaid shaft receives its motion. lThe fulling-machine may also-be constructed` with one-tub and one set of beaters. If desired, the drivingshaft can be extended, sc that a number of fulling-machines will bdriven'from the snne shaft, in the saine manner as nowapplied to the old hole-fullen'with that' di'ii'erence, however, that in the old fulling-mill the beaters are stopped, .while in my Afulling-mill the tubs'are .moved towards nndfrom the beaters,lwhile the vmotion of said beatersrcontinues v This failing-mill is applicable for fulli'ng cloth of every description, also foritll fabrics of wool, or wool and cotton mixed, or of cotton alone, also for leather and so forth, aud it can also beused with advantage for washing clothes of any description.

' Having thus described my invention, ivhat I claim as new, and desire to secure by lLetters Patent, is

L The toothed segments c,'gearing in pinions e, in combination with. the beater-sand tub or tubs of a. fallingvmill, substantially as and for the purpose set forth.,

2.\, The springs v Orffin combination with the ltub or 'tubs of a. falling-mill,substantially as and for the purpose described.

3. The springs `7c and adjusting-screws c, in combination with the eccentrics L and beaters B of a fullingmili, substantially as and for the purpose setforth.
